PGBT Western Extension (PGBT WE)

The Bush Turnpike Western Extension provides an 11.5-mile link in the growing loop around Dallas.  The corridor consists of the tolled main lanes, known as the Western Extension, and the frontage roads, which are referenced as State Highway 161.  The new corridor features cashless tolling on the main lanes in each direction between just north of I-30 south to I-20.
Phases 1-3 of Western Extension opened to traffic in 2009 and 2010 under the direction of the Texas Department of Transportation. 
The NTTA formally approved Phase 4 of the project on Feb. 26, 2010, authorizing a toll equity loan agreement with TxDOT and a commitment of an up-front payment of $458 million.  Learn more about the project’s unique financing, and view the certification under Section 1511 of The American Recovery and Reinvestment Act (ARRA).


Phase 4 of the Western Extension of the Bush Turnpike opened to traffic in October 2012.
With the opening of the newest portion of the roadway, the entire length of the PGBT has increased from 40 to 52 miles.
On March 1, 2013, the NTTA held an opening event commemorating the entire PGBT in Grand Prairie. Some of the special dignitaries attending the event included Federal Highway Administration Administrator Victor Mendez, Texas State Representative Roberto Alonzo and Dallas County Judge Clay Jenkins. Keynote speaker Texas Congresswoman Eddie Bernice Johnson was unable to attend the event, but addressed the audience with a video-recorded message.

Cost Estimate

NTTA estimated cost for Phases 2, 3 and 4: $534.6 million (excluding the cost of future expansions).
